2.1.2 Performance
• 100/100MHz Synchronous Host/DRAM Clock Support: CPU frequency can
operate at 100MHz while system memory operates at 100MHz.
• High-Speed Data Transfer Interface: This motherboard with its chipset and
support for UltraDMA/66 doubles the UltraDMA/33 burst transfer rate to
66.6MB/s. UltraDMA/66 is backward compatible with both DMA/33 and DMA
and with existing DMA devices and systems so there is no need to upgrade
current EIDE/IDE drives and host systems. (UltraDMA/66 requires a 40-pin
80-conductor cable to be enabled and/or for UltraDMA Mode 4.)
• Concurrent PCI: Concurrent PCI allows multiple PCI transfers from PCI mas-
ter buses to memory to CPU.
• SDRAM Optimized Performance: This motherboard supports the new genera-
tion memory, Synchronous Dynamic Random Access Memory (SDRAM), which
increases the data transfer rate to 800MB/s max using PC100-compliant SDRAM.
• ACPI Ready: ACPI (Advanced Configuration and Power Interface) provides
more Energy Saving Features for future operating systems (OS) supporting OS
Direct Power Management (OSPM) functionality. With these features imple-
mented in the OS, PCs can be ready around the clock, yet satisfy all the energy
saving standards. To fully utilize the benefits of ACPI, an ACPI-supported OS,
such as Windows 98, must be used.
• PC 99 Compliancy: Both the BIOS and hardware levels of the motherboard meets
PC 99 compliancy. The new PC 99 requirements for systems and components are
based on the following high-level goals: Support for Plug and Play compatibility
and power management for configuring and managing all system components,
and 32-bit device drivers and installation procedures for Windows 95/98/NT.
